According to IS 456.
31.1.1 For the purpose of this clause, the followingdefinitions shall apply:
a) Column strip - Column strip means a design strip having a width of 0.25 L2, but not greater than 0.25 L1 each side of the columncentre- line, where L1 is the span in the direction moments are being determined, measured centre tocentre of supports and' L2 is th span transverse to measured centre to centre of supports.

As per In IS456 - 2000 Clause 31.1.1.
We have to take column strip is 0.25L2 but not less than 0.25L1.
That means if you do (1/4)L1 or (1/4)L2 = 0.25 * length of panel.
I think the correct answer is [A].

@Madhu.
The question is not asking about drop panel.
Here clearly mention column strip Same as in clause 31.1.1 a) of IS 456. So, I think A is the correct option.

1 column strip =L/4.
There are 2 column strips on one side.
So we take column strips=2 * L/4=L/2.
So, the given is the correct answer.

As per 1956:2000.
The effective width of a column strip of a flat slab is taken as half the width of the panel.

Half the width of the panel Or 2 times one-fourth the width of the shortest panel. Please explain.

Answer is correct. Refer 31.2.2, it is half the width of panel (drop panel), not slab width.

So with this, what is the width of the half middle strips given unequal span lengths?
